Release 2.0.0

[Penlect]

Added

• Two new keyword arguments to rpack.pack() named max_width and max_height used to optionally set restrictions on the resulting bounding box.
• Exception PackingImpossibleError.
• Function rpack.bbox_size.
• Function rpack.packing_density.
• Function rpack.overlapping.
• Build dependency to Cython.

Changed

• Improved rpack.pack() algorithm to yield higher packing density.
• Improved rpack.pack() time complexity; ~x100 faster compared to version 1.1.0.
• The rectangles are sorted internally in rpack.pack() so the input ordering does no longer matter.
• Renamed rpack.enclosing_size to rpack.bbox_size.

Removed/deprecated

• Function rpack.group(). It is still available at rpack._rpack.group() but will be removed completely in the future.
• Old implementation of rpack.pack(). It is still available at rpack._rpack.pack() but will be removed in the future.

Other changes

• Updated Sphinx documentation.
